Inside the mechanical parts, the four “LoRa-LOC-FDx” modules version is composed of 9
boards:
4 back panel boards
4 LoRa-LOC modem boards
A single front-end full-duplex radio board
The back panel boards connect the four LoRa modems together and also to the CPU module.
This board is the same as the one used in the WAN module and single LoRa module. The
board will not be further more detailed.
Four Lora LOC boards are used. They integrate the AD936x transceiver and DSP as
demodulators, as described previously.
The front-end board embeds the radio transmitters and receivers to support the ISM915
unlicensed bands (902-928MHz).
The front-end board is connected to the LoRa-LOC modules trough SMB RF connectors and a
HE10 14 contacts. The first Lora-LOC board is plugged directly on the front-end board
through the SMB connectors. The other LoRa-LOC boards are connected to the front-end
board through SMB coaxial cables.
